Wouldn't this be essentially the same as an "amplifier" audio unit
with unity gain?

Hi,
I'm a Audio Unit beginner, although I have _some_ Core Audio
experience, and in the coming period I'll be working on a Mac OS X
audio application. This app needs to do essentially two things:
analyze audio files and process audio files.
The processing consists of adjusting the volume, pitch, etc. This
seems to be a task well suited for Audio Units, and I will be using
some third party effects unit in this stage.
During the analysis phase the goal is to measure the music's tempo,
max. volume, and other parameters which are needed during
processing. These tasks don't modify the audio data, so if I would
perform these steps using audio units, the 'in' data would be
copied to the 'out' channel verbatim. In the Audio Unit
documentation I haven't found any examples of using Audio Units in
this way but I think it is possible. I imagine that I could set up
a chain of analysis units and 'pull' the audio data through it.
Afterwards I'd read some custom unit properties to retrieve the
results. At this moment I'm unsure if this is indeed a viable
approach, which base class I should be extending, etc.
Any opinions, suggestions, or pointers on using Audio Units for
analysis are welcome.
patrick
